A mulch fire that ignited off of I-75 in North Fort Myers on Saturday evening was contained by Sunday morning.

The fire started burning right off of the highway near mile marker 143 at around 5 p.m. at the MW Horticulture Recycling Facility.

The owner of the business said she lost more than $250,000 of inventory, and that the fire started around logs that hadn't been grinded into mulch yet. She said she believes the cause of the fire is suspicious.

More than ten different agencies responded to the scene to help extinguish the flames. Fire crews said the biggest challenge was putting out the fire that caught onto raw material.

The initial fire was just two acres, but quickly spread to more than six acres.

Crews worked well into the night, and weren't able to contain the fire. Their overall goal was to make sure that it didn't grow any larger than it already was.

"Twenty-five pieces of equipment working, we've used a helicopter from Charlotte County Sheriff's Office helping us drop some water on it. We've used two ambulances from EMS and we haven't turned the fire at all, we've just held it," Fire Chief Larry Nisbet with the Bayshore Fire Rescue said.

One major concern was the smoke fuming from the fire over the highway. The Florida Highway Patrol was on hand in the area ensuring traffic moved smoothly.

Crews returned on Sunday morning, and expect to put the fire entirely out today.
